MACHINE FOR ROLLING RODS OR WIRE.

SPECIFICATION forming part of Letters Fatent No. 599,337, dated February 22, 1898.

Application filed February 3, 1897- Serial No. 621,759. (N model.)

To all whom it may concern:

Be it known that I, ABEL KENWORTHY, a citizen of the United States,residing at Taterbury, in the county of New Haven and State of Connecticut, have invented certain new and useful Improvements in Machines for Rolling Rods or Wire, (Case B 5) and I do hereby declare the following; to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to the manufacture of rods and wire, and has for its object to produce a machine for reducing rods and wire [5 by rolling which shall be simple and easy to operate and through which each pass of the rod or wire results in two reductions and elongations instead of one and the passes being made very rapidly, thereby greatly decreasing the cost of production-a machine,

in brief, which will produce the highest grade of wire at reduced expense.

\Vith this end in view I have devised the novel machine of which the following descrip- 2 5 tion, in connection with the accompanying drawings, is a specification, numbers and let ters being used to designate the several parts. Figure 1 is a side elevation of the machine complete; Fig. 2, an end view as seen from the right in Fig. 1, the shield being removed and the coiling-stud in section; Fig. 3, a section on the line so 00 in Fig. 1; Fig. 4, a detail sectional View illustrating the operation of the pointing-rolls; Fig. 5, an enlarged fragmentary plan view illustrating the relative position of the pairs of reducing-rolls, the guides, and the coiling device. Fig. 6 is an elevation of the coiling device detached. Fig. 7 is a detail plan, partly in section, on line y yof Fig. 1. Fig. 8 is a detail section on line .2 z of Fig. 2.

The essential feature of this machine is that I reduce rods or wire by passing rods orlengths thereof between two pairs of rolls, the wire or rod in starting being passed through the first pair of rolls, which are non-driven, and into engagement with the second pair of rolls, which are driven, the second pair of rolls, in addition to reducing the rods a second time,

acting to draw the rods through the first pair of rolls,which impart to the rods a first reduction. I thus perform two reducing operations at each pass of the rod by means of a pair of driven rolls and a pair of non-driven rolls. In practice the rolls of the second pair are grooved. By providing each roll in this pair with larger and smaller corresponding grooves and by making the rolls of the first pair adjustable I am enabled to perform two additional reducing operations upon the same rod or rods by passing them a second time through the machine. The rods are ordinarily annealed before being given a second pass. They are, however, passed through the machine black-that is, as they come from the annealing-furnace-the ordinary operations of pickling and washing being wholly unnecessary with my novel machine. It is obvious that the length of the rod will be greatly increased, as a matter of fact doubled, more or less, by the first pass through the machine. Byprovidingaspeed-changingdevice, however, which enables me to give to the second pair of reducing-rolls a much higher rate of speed at the second pass, I am en abled, although the length of the rod will have been greatly increased by the first pass,

to make the second pass of the rod quite as quickly as the first. The machine may be quickly changed from the low speed to the high speed, and vice versa, and the position of the first pair of rolls may also be quickly changed when it is required to give a quantity of rods a second pass, or, having given the second pass to a lot of rods, to change it 8 5 back to the slow speed for the purpose of giving the first pass to another lot of rods.

For convenience in description I will use the term rod, although it will of coursebe understood that in the shops the term wire 9cis ordinarily used after the rods have been reduced to acertain diameter.

In practice my novel machine is adapted for use in reducing either large or small rods or wire, and, moreover, it enables me to re- 5 duce the rods very rapidly, as, owing to the fact that the first pair of reducing-rolls are non-driven, I am enabled to drive the second pair of reducing-rolls at a relatively high rate of speed during the first pass and at double the speed, more or less, during the second pass.

1 denotes a driving-pulley which is adapted to turn loosely on a shaft'2 or to be coupled therewith by means of a clutch A.

3 denotes a pinion which is fixed to driving-pulley 1 and is adapted to turn with it on shaft 2 or to be coupled to the shaft with the pulley by means of the clutch.

4 denotes a shaft which carries a gear-wheel 5, which meshes-with the pinion 3 and a pinion 6, which is secured to said shaft by means of a key 7, so as to turn with the shaft, leaving said pinion, however, free to be moved longitudinally on the shaft, so that said pinion may be moved into or out of engagement with a gear-wheel 8, which is fixed to shaft 2.

9 denotes the yoke of an operating-lever, said lever not being shown, by which pinion 6 may be moved longitudinally on the shaft. The arms of the yoke are shown as carrying pins or rollers 10, which engage a groove 11 in a hub 12, which is formed integral with or rigidly secured to pinion 6. 13 denotes a similar yoke, the lever not being shown, the pins 14 of which engage a groove 15 in a cone 16, which is secured to shaft 2 by means of a key 1'7 and turns with the shaft, leaving said cone,

' however, free to be moved longitudinally on the shaft, so that said cone when moved in one direction by the yoke will operate clutch A and connect belt-pulley 1 and pinion 3 with shaft 2, and when said cone is moved in the opposite direction the holding mechanism of the clutch will be released, thereby disconnecting belt-pulley 1 and pinion 3 from shaft 2.

It is not considered necessary to describe the clutch in detail, as any ordinary frictionclutch may be made to serve the purpose, it being simply required to provide any suitable clutch that may be operated readily to connect and disconnect belt-pulley 1 and pinion 3 from shaft 2.

The operation of this driving mechanism is as follows: When it is desired to pass a lot of rods through the machine at the slow speed, clutch A is operated to disconnect belt-pulley 1 and pinion 3 from shaft 2. Motion is therefore communicated from pinion 3 to gear-Wheel 5 on shaft 4 and from pinion 6 on shaft 4 to gear-wheel 8 on shaft 2, it being understood that this gear-wheel is at all times fixed to the shaft, but that belt-pulley 1 and pinion 3 are now turning independently of shaft 2. When it is desired 'to pass a lot of rods through at the high speed, belt-pulley 1 is connected to shaft 2 by means of clutch A and pinion 6 is moved from the position shown in full lines in Fig. 1 to the position shown in dotted lines in said figurethat is, wholly out of engagement with gear-wheel 8-so that 1shaft 2 is now driven directly from belt-pul- It will be noticed that no matter whether the machine is being driven at the fast speed or the slow speedthat is to say, whether pinion 6 is or is not in engagement with gearwheel 8-pinion 3 is always in engagement with gear-wheel 5, so that shaft 4 is always rotated. This shaftis the driving-shaft for the mechanism which flattens or points the end of the rod and which I will now describe. At the inner end of shaft 4 is a bevel-pinion 18, which meshes with a bevel gear-wheel 19 on a vertical shaft 20, which also carries a gear-wheel 21, which meshes with a similar gear-wheel 22 on a short vertical shaft 23. These shafts are journaled in boxes carried by a casting 27, which is shown as bolted to a bed 28, supported by legs 29. This casting is also bolted to standards 30 30, which rest upon the bed and in which shaft 2 and the other roll-carrying shaft 35 are journaled, as will be again referred to. These shafts 20 and 23 carry pointing-rolls 24 24. Each of these rolls is provided with a curved enlargement which forms a pointing-surface a and with a greater curved enlargement which forms a pointing-surface Z). (See Fig.4 in connection with Fig. 1.) Before giving the first pass to a lot of rods they are all flattened or pointed at their ends by being passed between the pointing-surfaces a a of the pointing-rolls. The rods are passed in, as indicated by dotted lines in Fig. 4, when the reduced portions of the rolls are opposite each other. The rolls rotate in the direction of the arrows and the rods are pointed by being compressed between the enlargements on the rolls, said rods being forced out again by the rolls.

It will of course be understood that the rods are greatly reduced in diameter and increased in length by the first pass. It is consequently necessary to repoint the rods before giving them the second pass. This is done by passing each rod between the pointing-surfaces b b of the pointing-rolls.

25 25 denote the first reducing-rolls, and 26 26 the second reducing-rolls. The first reducing-rolls are journaled in upper and lower boxes 31, the upper boxes only being shown in Fig. 7, said boxes lyingin upper and lower frames 32, which are removably placed in ways 33 in standards 34, in which shaft 2 and the other roll-carrying shaft 35 are journaled, the end boxes only of these shafts showing and beingindicated by 36 in Fig. 2. The first reducing-rolls 25 25 are made adjustable, the purpose of which will presently be described, by means of blocks 37. (See Fig. 7.) In adjusting the first drawing-rolls the upper and lower boxes 31 are moved in the frames and are locked in position after adjustment by means of these blocks, the heads of which are longer than the width of the opening in the frame-2'. e., T-shapedso that they will not pass down into the opening in which the boxes lie. The first reducing-rolls are shown as placed vertically. The second reducingrolls are carried by shafts 2 and 35. Each of these rolls is provided with a groove 0, by which the rod is reduced at the first pass, and a groove d, by which it is reduced at the second pass. Shafts 2 and 35 are both ordinary jointed shafts. The boxes of one of these shaftsshaft 35 in the present instance-are made adjustable in standards 34 by means of an ordinary adjusting device, which I have indicated by B. This adjusting device is in common use and is not thought to require description in detail.

It is sufficient for the purposes of this specification to say that one or more of the screws of the adjusting device are provided with angular ends 38 to adapt them to receive a wrench or key. To adjust the upper roll 26 up or down, as may be required, in changing from larger to smaller rods, or vice versa, the operator applies a wrench or key to the squared end of a screw and turns the gearwheels of the adjusting device in either direction, asmay be required, thereby raising or lowering the boXes in which said shaft 35 is journaled. In use, after the rod has passed the first reducing-rolls it enters a guide 39, by which it is conducted to the second reducingrolls, and after passing the second reducingrolls it enters a guide 40, by which it is conducting to the coiling device, which as a whole I have indicated by C, for the reason that any ordinary or preferred coiling device may be used. In the present instance I have shown a coiling device consisting of grooved coiling-rolls 41 41, which receive the rod from guide 40. These rolls are driven by means of a belt (not shown) passing over a belt-pub ley 42 and intermediate gearing, which is shown in Fig. 2, but which I have not thought it necessary to illustrate in detail. 43 is a non-driven roll against which the end of the rod comes in contact as it passes from rolls 41 and by which the rod is deflected, so that it will coil about a stud 44.

45 denotes a shield (see Figs. 5 and 6) which is provided with a cut 46, and the upper portion of which, at one side of the cut, is curved outward and then turned upward, as at 47. This shield is supported by stud 44 and by the stud 48, on which roll 43 is journaled. The rod as it passes from rolls 41 is deflected by roll 43 and caused to coil about stud 44, portion 47 of the shield acting to protect the rolls and to cause the rod to coil about the outer end of stud 44. The upper coiling-roll 41 may be adjusted up or down, as may be required, by a screw 49, which engages the boX of upper roll 41, (not shown,) and is provided with a hand-wheel 50, for convenience in adjusting the roll.

The operation of the machine as a whole is as follows: Suppose that it is required to reduce a lot of rods the full capacity of the machine. The operator either points the entire lot by passing them between the pointing-surfaces CL CL of the pointing-rolls, or else one operator points the rods and another takes them and passes them through the ma chine.

The reduced or pointed portion of the rod is of a length sufficient to enable the end of the rod to reach the grooves c in rolls 26 and be grasped by said rolls before the shoulders at the end of the reduced portion have reached rolls 25. As soon as the rod begins to be drawn in the attendant leaves it and it will be passed through and coiled, two reductions having been given to it.

In practice there will be a stock of rods run down through the grooves 0 before the changes are made to further reduce the wire with the same machine. Such changes consist in ad j usting the rolls 25 by means of the blocks 37, as hereinbefore described, and in changing the guides 39 and 40 in order to bring the latter in alinement with the grooves d of the rolls 26 and in making the changes in the speed-gear, as before described, if the latter is desirable.

The end of the guide 40 near the rolls 26 rests on a cross-piece 51 between the standards 34 (see Fig. 8) and is held between two blocks 52 and 53 of different widths, bolted to said cross-piece. these blocks the end of the guide is held in the position shown by dotted lines in Fig. 5. The position of the guide 39 is similarly changed on its support 54. (Shown in Fig. 7.)
